9 Claims. (01.112-138) The invention relates to new and useful improvements in a binder support for sewing machines. In the application of George Sauer, Serial No. 590,277, filed February 1, 1932,'Patent Number 1,949,332, there is shown a binder support for a sewing machine of the type wherein the work support terminates and is spaced away from the standard, and the binder is mounted on the standard and supported so as to properly direct a binding strip about the edge of a fabric section passing over the work support. In this application there is also shown a means whereby the binder may be shifted from an operative to an inoperative position and locked in both of said set positions. The present invention is an improvement in the mounting for the binder disclosed in the application referred to, and has for an object to provide a binder support and locking means which permits the binder to be quickly withdrawn by grasping the latch which looks it in operative position and by a pressure on the latch in the same direction that releases tht latch.

A further object of the invention is to provide a binder support of the above type wherein the binder when returned to operative position will be automatically'locked in said operative position.

A still further object of the invention is to provide a support for the binder which includes means whereby said binder may be shifted toward and from the line of feed and also raised and lowered relative to the plane of the fabric for the proper positioning of the binder.

These and other objects will in part be obvious and will in part be hereinafter more fully disclosed. I V

The sewing machine to-whichthe binder is shown as applied includes a -supporting bed l on which'is mounted a standard 2 carrying a housing 3 in which is mounted the main actuating shaft driven from the belt wheel-4i Also, mounted in this housing is the needle bar-carry ing a needle 5. The "shaft is located in' a line lying in a vertical plane which extends in the general direction of the line of feed and is in clined thereto. Cooperating with the needle be neath the work support is a looper mounted-on a carrier 6 and operating in the usual manner.

This type of machine to which the invention is shown applied is disclosed more fully in the patent granted Norman V. Christensen and Frederick F. Zeier, March 25, .1930, No. 1,751,508, and their application Serial No. 590,228, filed February 1, 1932, Patent No '1,952,'534. e

Mounted on supporting members'formed' as a; part of the bed I is a work support 1. The Work support 7 terminates "on a line-"located slightly tothe right of the line of feed and the stitching point, as viewed in Fig. 1, and it extends to a suitable distance to the left thereof, thus forming a support for the fabric being stitched. Attached to the work support is a throat plate 8 which is raised above the'upper face of the work support, and the fabric slides upon to and across the throat plate. 'Thethroat plate is inclined at the front end thereof to aid in the directing of the fabric up on to the same. The fabric is held on the throat plate by a presser foot 9. Located at the right of the work support l -is a fabric supporting plate It. Said fabric supporting plate I0 is pivotally mounted at H on a bracket l2 which is attached to the bed. This extension It] extends all the Way from the front end of the work supportto a point adjacent the front end of the throat plate onthe same level as the work support. This extension has a depressed portion in rear of a line disposed adjacent the frontend of the throat plate, and this provides a recessor space for the mounting of a binder.

The binder illustrated in the drawings is shown at l3 and is of the English binder type. In this type of binder, the binding strip which passes through the binder is inverted and then directed aboutthe edges of the fabrics'ection being bound. The binder, therefore, has its longitudinal-axis extending at right angles to the lineof feed. The binding strip passes through tension posts l l'c'arried by the bracket I2, and then enters thereoeiving end l5 of the'binder." The binding strip is folded upon itself and then inverted at the inclined portion l6 of the binder, and is then guided in the direction of the feed of the fabric sections. The fabric section being bound passes through the lefthand end of the binder as viewed in Fig. 1, and this is what lays the upper and lower portions of the binding about the edges of the fabric. 7 This extension ID is held in closed position by a-spring'latch IT. It may be readily'withdrawn and swung about the pivotal support H therefor, in order to give access to the parts of the machine therebeneath and also to give more ready access to the bindenif desired. The binder I3 is mounted on the support J3 to which it is secured by screws I9, l9. These screws pass through an elongated slot 28 in the supporting member and serve as a means whereby the binder may be adjusted toward and from the fabric section for causing the binding strip to overlie to a.

greater or less extent the fabric section being stitched This supporting; member Ht is in turn mounted on a supporting bar 2 i. The supporting member is providedwith vertical slots 22, 22, and screws 23, 23 passing therethrough serve to clamp said memberj 8 to the bar and permit the member |8tobe raised and lowered and this will raiseor lower the binder relative to the plane of the work support. *The supporting bar 2| is attached to: a bracket 2%.; This bracket 24' is shown in per spective Fig. 6. Iticonsists of. a vertical portion having horizontal slots 25,; 25 therethrough, and screws 26 passing-throughcj these slots secure the: bracket to the standardZ of the machine. The bracket has .a horizontal portion 240, provided with a longitudinal slot 21.. There is a recess 28 at the outer endof the slot. which extends around into the vertical portion of the; bracket.

Attached to they supporting bar 2| is a plate.

2! which fits within. the slot 2?. This'plate is of substantially thejsame thickness as the horizontal portion 24a of the bracket. Attached to the inner'face' ofthe plate 29 is a spring member 30. Said member 30 is rigidly fixed to the plate. 29' by means of screws 3|. The ends of. this spring member 30 are'curved outwardly away from the bracket as indicated at 32,. 32. spring'memher is of suflicient width so that it overlies the sides of the slot 21 and bears against the rear face of this horizontal section 24a,v oi the bracket. .The recess 23 is of sufficient height to permit thespring member 30 to pass therethrough, and therefore, the binder may be attached to the bracket by insorting the end 32 of this spring member in the recess 28,,and passing the plate 29 intothe slot 21.. This provides a means whereby the binder supported sothat it maybe moved in an end wise direction. It may be moved to an operative position for guiding a binding strip about the edge of afabric section, and it also may be retracted and moved to an inoperative position while still supported by the bracket, or it may be disconnected from the bracket. The slots 25 in the bracket permit said bracket to be adjusted toward the front of the machine or toward the rear of the machine, and this enables the delivery end'of the binder to be set closer to or further away from the needle. a

A latch means is provided for holding the binder in its operative position. This latch means includes a latch 33 which is pivoted at 34 to the supporting bar 2|. The latch is provided with a handle member 35 and with a locking nose member 36. The horizontal portion 240. of the bracket 2t is provided with a recess 31. A spring 38 coiled about the supporting screw 33 attached to an the slot 21.

abutment pin 40. This spring rests against the latch and the end of the spring is seated in a groove in the latch. The spring normally turns the latch in a counter-clockwise direction. When it is desired to release the binder and move it away from its operative position, the operator presses on the handle member 35 so as to move the latch in a clockwise direction. This will lift the nose from the recess 31, and thus release the supporting bar 2| so that it may be moved along There is a stop 33a which limits the movement of the latch on the supporting bar 2i. A pressure on; the handle member 35 of the latch to the right, asviewed in Fig. 1, which is the necessary pressure to release the latch, will also force the supporting bar to the right and withdraw the binder to an inoperative position. Further movement of the handle member 35 to the right will entirely disconnect the binder from the bracket 24. When it is desired to return thezbinder to. its operative position, the operator may press on the handlemember'or on the end of the bar 2|, and move the binder up to the fabric section. The spring will causethe'latch to automatically engage the recess 31 and thus hold the binder in its set operative position.

Itis obvious that minor changes in the details of construction and the arrangement of the parts may be made without departingfrom the spirit of the invention as set forth in the appended claims. a
